TYPE-WRITI NG MACH IN E.

SPECIFICATION forming part of Letters Patent No. 465,021, dated December 15, 1891. Application filed November 20, 1890. Serial No. 372,010. (No model.)

To a/ZZ whom it may concern: 3

Be it known that we, GEORGE A. HILL and CHARLES M. HILL, citizens of the United States, and residents of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Vriting Machines, of which the following is a specication.

Our invention has for its main object to provide a construction by which the typewriting machine is capable of printing from a continuous roll or web of paper; and to this end it consists in the features of construction and combinations of devices hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a plan view of a portion of a type-writing machine embodying our improvements. Fig.

2 is a vertical section taken through the rollV of paper and on the line a: :r of Fig. 3. Fig. 3 is a side view of a portion of a type-writing machine embodying our improvements. Fig. i is a vertical cross-section through the carriage and the upper part of the machine. Fig. 5 is a vertical section taken at the line y y of Fig. 2; and Fig. 6 is a detail View, in elevavation, of one end of the roll-supporting core.

In the several views the same part will be found designated by the same numeral of ret`- erence.

1 designates the frame-work of a type-writing machine, and 2 the paper-platen thereof. rlhe latter, as usual, is mounted to rotate in a frame or carriage composed of the end bars 3 and 4 and front and rear bars 5 and G, respectively. The front bar 5 is provided with a bracket 7, which contains an anti-friction roller S, that travels upon a track or Way 9, affixed to posts rising from the framework. The said bracket is also provided with a'paper-guide 10, which partially encircles the platen at its front side and at about the middie of its length. The rear bar 6 passes through eyes or bearings 1l in a yoke l2 and forms an elongated pintle or shaft about which the carriage audits appendages may be turn ed up or vibrated, the yoke being incapable of turning by reason of its peculiar mounting on the parallel guide-rods 13 and 14, all as common in that type of machines known as the Oaligraph.

For the sake of clearness We have omitted to show the letter-spacing mechanism and the carriage-driving mechanism, as well as other necessary parts of a fully-equipped type-writing machine, and in carrying out our invention any of the well-known and suitable letterspacing and carriage-driving mechanisms may be employed.

On t-he back bar 6 is mounted near each end a bracket 15, to which is attached one end of a spring 16,which is curved to extend around the under side of the platen .at its end and which serves as a guide for the paper during the feeding operation. About the center of each of said springs is soldered or secured a bracket 17, in which brackets the ends of the feeding or pressure roller 1S are mounted or journaled, and to said brackets the ends of a paper-scale 19 are attached, all in about the usual manner.

Secured to the back bar 6 by suitable couplings or clips is a paper-table 20.

Attached to the frame-work by screws on opposite sides of the machine or made integral with said frame-work is a supplemental frame-work or support 21, arranged in rear of the type-writing machine proper and terminating in two upwardly-projecting arms 22 and 23, each having a half-round groove or open bearing 24 for the reception of the ends of `a round rod 25, which is longer than the carriage guide-rails and which is arranged parallel therewith. Upon said rod 25 is mounted the roll of paper 26 to be used with the machine. The roll is preferably provided at its ends with hollow wooden tapering plugs 27, through which is inserted a tubular core 23, having perforated end pieces 29 and 30, which bear upon the rod 25. The end piece or bcaring29 is elongated and grooved, as at 31, Jforming shoulders 32 and 33, between which is iitted the biturcated end' 34 of an arm 35, pivoted or hinged to the back bar 6 of the papercarriage. By means of said arm the roll of paper is connected to the paper-carriage to travel therewith and in its movements to bear always a 'fixed position relatively to the paper-platen. The roll is prevented from IOO moving endwise independently of the core by means of pins 36 and 37, the pins 36 being attached to the end piece 29 and the pins 37 to a ring or band 38, encircling one end of the core or tube and provided with a bayonetslot 39, which is adapted to co-operate with a projecting screw or pin 40 in the core, thus locking the band and the pins 37 in position. The roll is prevented from unwinding too freely by a forked spring 41, screwed to the arm 35 and bearing with the proper degree of pressure or force upon the'end piece 29 of the core.

In order to put on or take off a roll of paper, the band 38, with its pins 37, is detached, the screw or pin 40 removed, and the guiderod 25 lifted out of its supports or bearings. The devices at the other end of the core need not be disturbed. Supposing the roll to have been properly mounted, as illustrated, the leading end of the web of paper is passed down over the paper-table and between the platen and feed-roll and the several paperguides to the desired extent. The writing may then be begun, and as the carriage travels to the left of the operator the roll is carried along in unison therewith by reason of the rigid connection between the carriage and said roll. In order that the weight of the roll and its accessories shall not add materially to the finger-key tension of the machine or to the driving power required We make the arm or support 22 slightly low-er than that marked 23, so that the guide-rod 25 may be inclined toward the left and the roll thus assisted in that direction by the force of gravity during the operation of the finger-keys in writing. When the end of the line has been reached,

. the carriage and roll are returned by a pull When the carriage is travelingto the left, the

arm 35 at its hooked or bifurcated end bears against the shoulder or liange 32, andthe roll is thus forced to move with said carriage, and

when the carriage is being returned to the right the hooked end of the arm bears against the shoulder or flange 33 and forces the roll also to the right. Then the writing has been finished, the paper may be severed at any desired locality. Ve prefer to have the paper perforated transversely at uniform distances, so that when severed after having been written upon the sheets may be all of' equal length. The paper may of course be prepared with any desired printed matter or heading.

In practice thus far we have used telegraphblanks printed in a continuous roll and perforated crosswise between each blank and have found that message after message may be written until the roll has been exhausted after the leading end of the roll has been once properly inserted between the feed-roll and paper-platen, dac. As the paper is progressively unwound it is fed up over the platen into position for ready severance. The pins 36 and 37 not onlyprevent endwise movement of the roll bodily independent of the core, but,-

by reason of their length, they serve to confine the side edges of the paper and assist inl feeding or delivering the paper to the platen in a true and perfect condition.

When it may be desired to use the machine in the usual way with loose sheets, the hooked end of the arm may be detached from the core or roll-support and allowed to rest on the carriage.

What we claim as new, and desire to secure by Letters Patent, is

l. In a type-writing machine, the coir'lbina-V tion, with the platen and its carriage, of an elongated stationary guide-rod arranged parallel with the path of movement of the papercarriage, and a roll of paper connected to the carriage and arranged to turn about and slide longitudinally upon said fixed guide-rod.
